Slide Out animation broken on v1.4.0

Slide Out animations do not slide all the way off screen starting on v1.4.0

I use Animatable SlideOut animations for screen transitions, and after updating, the screens do not slide all the way out of frame. For testing, I applied a simple SlideOut animation to a standard button, and it only slides 1/3 of the way off.

For now, I've reverted to 1.3.3 which doesn't have the issue.
